Yes, in most cases you do. Many institutions offering a Polytechnic in CSE College in India prefer students who have studied Mathematics and Science in Class 10. These subjects act as a strong foundation because Computer Science involves logical thinking, problem-solving, and understanding technical concepts that often connect with basic maths and science principles.
While a few colleges may still accept students who have passed Class 10 without specific subject requirements, having Maths and Science makes the learning process much easier. Topics like programming logic, algorithms, networking, computer hardware, and data structures become simpler when you already have basic mathematical understanding.
Colleges also consider that students with Maths and Science are better prepared for the technical nature of the CSE diploma. So even though it may not be mandatory everywhere, it is highly recommended because it increases your chances of admission and helps you perform well throughout the 3-year course.
